Description
Purvalanol A (212844-53-6) is a cyclin-dependent kinase inhibitor. IC50s= 4, 70, 35, 75 and 850 nM for cdc2/cyclin B, cdk2/cyclin A, cdk2/cyclin E, cdk5/p35 and cdk4/cyclin D1 and respectively.1?Reversibly arrests synchronized cells in G1 and G2 phase.2?Induces ER stress-mediated apoptosis and autophagy in colon cancer cells.3?Suppresses Src-mediated transformation by inhibiting both CDKs and c-Src.4?In cells transformed with MYC, purvalanol A rapidly down-regulates survivin expression and induces MYC-dependent apoptosis.5?Cell permeable.
Uses
Inhibitor of human CDK1 (IC50=4nM), CDK2/cyclin A (IC50=70nM), Cdc2/cyclin B, CDK2/cyclin E (IC50=35nM), CDK4/cyclin D1 (IC50=850nM) as well as CDK5/p35 (IC50=75nM). More membrane permeable than purvalanol B.
Definition
ChEBI: Purvalanol A is a purvalanol.
Biological Activity
Cyclin-dependent kinase inhibitor. IC 50 values are 4, 70, 35, 850 and 75 nM for cdc2/cyclin B, cdk2/cyclin A, cdk2/cyclin E, cdk4/cyclin D1 and cdk5-p35 respectively. Reversibly arrests synchronised cells in G1 and G2, and inhibits cell proliferation and cell death.
